Which of the following best reflects a shield system?
a. A narrow excavation made below the surface of the ground.
b. A structure that is able to withstand the forces imposed on it by a cave-
in.
C. A series of horizontal levels or steps between vertical surfaces.
d. A system of structures that are inclined away from an excavation.

Answers

Answer 1
C, because a narrow structure evacuation below surface ground isn’t the best and a structure holding forces and isn’t to do with the question at all and d doesn’t matter if there include away or not

The image shows a reconstruction of a pyramid with a square base. What is the best estimate for the volume of the pyramid?

A.
1,460,040 m3

B.
2,433,400 m3

C.
4,380,120 m3

D.
7,300,200 m3

Answers

Answer:

B 2,433,400 m3

Hope that helped you

Based on the calcualtions, the best estimate for the volume of the pyramid is: B. 2,433,400 m³.

How to calculate the volume of a pyramid.

Mathematically, the volume of a pyramid is calculated by using this formula:

[tex]Volume = \frac{1}{3} \times base\;area \times height[/tex]

For the base area:

The area of a square is given by:

A = S²

A = 230²

A = 52,900 m².

Now, we can determine the volume:

Volume = 1/3 × 52,900 × 138

Volume = 2,433,400 m³.

Question 74
Which of the following would be required when towing a person on water skis
behind a PWC rated for two people?
A
power winch
B
reboarding ladder
С
rearview mirror (at least four inches by four inches)
D
rectangular red flag with a white diagonal stripe
Support

Answers

Answer:

C). rearview mirror (at least of four inches by four inches).

Explanation:

A 'rearview mirror' would be needed in case one is required to pull an individual on water skis after a PWC(personal watercraft) that is rated for carrying two persons only. This wide-angle mirror for rearview would allow the operator to monitor the person who is being towed constantly along with riding the ski at the same time. It is considered illegal to tow a person on a vessel without having a rearview mirror and at the same time, the limited capacity must also be followed strictly. Hence, option C is the correct answer.

A carbon resistor has a resistance of 976 ohms at 0 degrees C. Determine its resistance at 89 degrees C​

Answers

Answer:

1028.1184 Ohms

Explanation:

Given the following data;

Initial resistance, Ro = 976 OhmsInitial temperature, T1 = 0°CFinal temperature, T2 = 89°C

Assuming the temperature coefficient of resistance for carbon at 0°C is equal to 0.0006 per degree Celsius.

To find determine its new resistance, we would use the mathematical expression for linear resistivity;

[tex] R_{89} = R_{0} + R_{0}(\alpha T) [/tex]

Substituting into the equation, we have;

[tex] R_{89} = 976 + 976*(0.0006*89) [/tex]

[tex] R_{89} = 976 + 976*(0.0534) [/tex]

[tex] R_{89} = 976 + 52.1184 [/tex]

[tex] R_{89} = 1028.1184 \ Ohms [/tex]
